Charles H. Spurgeon on Psalms 74:2

Remember thy congregation. It is not without reason that they do not say, Remember us, but Remember thy congregation, not ours, but thine; nor that because it has now begun to be thine, but which thou hast purchased of old, the rod of thine inheritance which thou hast redeemed: likewise, this Mount Zion; not wherein we, but wherein thou hast dwelt. They had nothing which they could bring before an angry God with greater confidence, than the ancient lovingkindness shown to their fathers in former days. Musculus.
